tieleman / detect.js

Created April 25, 2013 07:39

Two quick 'n dirty JavaScript snippets to determine whether Flash/Silverlight are installed. Wrapped in try/catch blocks to prevent IE8 from throwing errors. Uses the "navigator.plugins" object in modern browsers and ActiveXObject for old IE.

	var hasFlash = false;
	var hasSilverlight = false;

	try {
	hasFlash = !!((typeof navigator.plugins != "undefined" && typeof navigator.plugins["Shockwave Flash"] == "object") \|\| (window.ActiveXObject && (new ActiveXObject("ShockwaveFlash.ShockwaveFlash")) !== false));
	} catch(err) {
	hasFlash = false;
	}

	try {
